To /LZZ wiz/07V., 7121/14/ concern:

Be it known that l, VERNON ROYLE, a citizen of the United States, and a resident of Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Tool-Holder, of 'which the following is a specilication.

My invention relates to tool-holders, and more particularly to tool-holders for use in connection with lining-bevelers, the object being to provide for gradually lifting the point of the cutter from its cutting position during the forward movement of the tool in order to taper the line of cut to a vanishingpoint when so desired and to further provide for bringing different tools into cutting position without the necessity of removing the tool from its holder and inserting another in its place.

A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure 1 is a plan view of a portion of the top of a lining-beveler, showing the tool-holder in its position in connection therewith. Fig. 2 is a vertical section of the same in the plane of the line A A of Fig. 1. Fig. 3 is a view in detail, showing the tool-holder in side elevation with its tools and operating-handle removed. Fig. 4 is a view of the same in edge elevation. Fig. 5 is a view in detail of one of the tools, and Fig. 6 represents in face and edge elevation one of the cheek-pieces for holding the tool in position.

Referring to the beveling-machine, to which the tool-holder may be attached for producing lines commonly located near the beveled edge of a photoengravure plate, the bed on which the plate to be operated upon rests is denoted by 1, the cutter-head for routing or beveling the plate by 2, and the bracket for supporting the arm which carries the lining-tool holder by 3. These parts, as well as the other parts of the machine, may be of any well-known or approved form, so that the swinging arm 4, which carries the lining-tool holder may be mounted in position to swing the tool-holder toward and away from the plate 5, shown in Fig. 2 as resting upon the table 1.

The arm 4 is provided with a laterally-extended pintle 6 and is received in the split bearing formed in the bracket 3, the parts of the said bearing being engaged by a screw 7 for drawing the parts together to apply to the pintle 6 of the arm 4 any desired means of friction. The arm 4 carries at its free end the lining-tool holder, which is indicated as a whole by 8. The body of the tool-holder S conveniently consists of a plate of metal of suitable thickness, in the present instance ob- -long in form, with its two diametrically opposite corners removed by a straight cut, leaving short planed faces 9 and 10 at two diametrically opposite corners, which faces are intended to contact with the surface of the plate, while the cutters are arranged with their cutting edges projecting outwardly beyond the faces 9 and 10.

The body of the holderS is recessed in proximity to the faces 9 and 10, one recess l1 for receiving the cutter 12 and another recess 13 for receiving the cutter 14. These recesses 1 1 and 13 are intended throughout a portion of their length at a distance back from the faces 9 and 10 to substantially fit the Shanks of the cutters, while in proximity to the faces 9 and 10 these recesses are widened, as shown at 15 and 16, to receive cheek-pieces 17 and 1S, the former for locking the cutter 12 in its position and the latter for locking the cutter 14 in its position. These widened portions 15 and. 16 of the recesses have inclined walls, the former denoted by 1Q and the latter by 20, located on the side of the recess farthest from the cutter, and the cheek-pieces 17 and 18 have correspondingly-beveled edges at their backs. ASee, for instance, the edge 21 of the cheek-piece 1S, Fig. 6, which coacts with the beveled walls of the recess to crowd the cheekpiece toward the cutter when the cheek-piece is forced home by its retaining-screw 22 passing through the cheek-piece and tapped into the body of the plate.

The body of the tool-holder is also provided with bar-springs 23 24, one for each tool, the said springs being fixed at one end to the edge of the holder by means of screws 25 26 and at their opposite ends engaging cuts 27, formed in Jthe faces ofthe tools` The ends of the springs engaged with 'the tools are forced toward the opposite edges of the body of the tool-hold er by means of screws 2S 29, passing through the springs and tapped into the opposite edges of the body of the holder, while the resiliency of the springs will move them away from the opposite edges of the holder whenever the screws 2S and 29 are unscrewed.

As the springs are forced toward the opposite edges of the holder they will carry with them the tools 12 and 14 to cause their cutroo IIO

ting edges to project the desired distance beyond the faces 9 and 10 to produce the depth of cut desired, and when the tools have been so adjusted to produce the depth of cut they may be locked securely in the adjusted position not only by the screws 28 and 29, but also by the cheek-pieces 17 and 18, which when their screws 22 are forced home Wedge themselves between the tools and the slanting back walls of their recesses.

T he body of the tool-holder is further provided with a socket 30 for the reception of an operating-handle 31, the said socket being ,open at its opposite ends to permit the handle 3]. to be inserted into either end of the socket at pleasure.

The body of the tool-holder is still further provided with a screw-threaded stem 32, which extends through the arm 4 and is provided with retaining-nuts 33 34 to secure the holder to the arm.

In use, as shown in Fig. 2, the cutter 14 is engaged with the plate 5, and the handle 31 is inserted in the socket in position to press the face 10 of the tool-holder into close contact with the face of the plate, thereby causing the cutter to cut the surface of the plate as the latter is moved, together with the table, beneath the cutter-hold er.

When it is desired to round the cut out to a fine line near its finish, the outer' end of the handle 31 may be pressed down upon sufficient to gradually tilt the cutter-hold er S on the heel of the surface 10, and this will cause the cutter 14 to gradually approach the surface of the plate while the plate is still in motion.

If it be desired to cut a second line of different width from the line cut by the cutter 14 either alone along the edge of the plate or in connection with the line cut by the cutter 14, the handle 31 is removed from its socket 30, the cutter-head is rotated a half-revolution to bring the face 9 in contact with the surface of the plate, which adjustment will bring the 'p cutter 12 into cutting position with relation to the plate, and the tool-holder may be manipulated as before by inserting the handle 31 in the opposite end of the socket 30.

By the foregoing simple construction the lining-cutter holder may be not only bodily removed through space in a curved path by the swinging of the arm 4, but may also be rotated on its own axis relative to the arm 4 to vary the depth of cut during the advance movement of the plate and also to bring into use any one of a plurality of cutters.

What I claim is- 1. A swinging arm movable toward vand away from the work and forming a support for a cutter-holder, a cutter-holder mounted in the said arm and having a rotary adjustment in a plane parallel with the plane in which the arm swings and a cutter carried by the holder, the .said holder being provided on its face toward the work with a bearing for guiding the cutter.

2. The combination with a support arranged to move toward and away from the work, of a cutter-holder mounted in the support in rotary adjustment and having its face toward the work flattened to maintain the cutter-holder in operative relation to the Work.

3. The combination with a swinging arm movable toward and away from the work, of a cutter-h older mounted in the arm and having a rotary adjustment in a plane parallel with the plane in which the arm swings, a plurality of cutters secured to the holder and means under the control of the operator for pressing the cutter-holder and cutter to the Work in its different rotary adjustments.

4. The combination with a suitable support, of a cutter-holder mounted in rotary adjustment on the support, a plurality of cutters attached to the holder, a handle for manipulating the cutter and means for removably attaching the handle to the cutter-holder in different positions relative thereto.

5. The combination with a suitable support movable toward and away from the work, of a cutter-holder mounted in rotary adjustment on the support and provided with a face for engaging the work, a cutter arranged to project beyond the said face of the holder which engages the Work and means for rocking the said holder on an edge of said face as a pivot to cause the cutter to lift from its work during the cutting operation.

6. rI`he combination with a cutter-holder provided with a recess for retaining the cutter, of a bar-spring attached to the cutterholder with its free end engaged with the cutter-shank, a screw for adjusting the free end of the bar-spring to move the cutter in a longitudinal direction in its recess and means for locking the cutter in its adjusted position.

7. The combination with a cutter-holder rovided with a plurality of cutters, means for locking the cutters in dierent adjusted positions withrespect to the cutter-holder and means for mounting the cutter-holder in different rotary adjustments, the said cutterholder being further provided with a socket opening in different directions, of a handle removably engaged with the socket, and adapted to enter the socket in different directions for pressing the cutter-holder and cutter toward the work in different adjustments of the holder.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 25th day of October, 1904.

VERNON ROYLE.
